Speciiication forming part of Letters Patent No. l, dated July 13, 1875;application filed June 3, 1875.

To all whom it 'may concern:

Beit known that we, ELMORE JOHNSON and JACKSON BARNES, of Burlington, inthe State of Vermont, have invented a Mop-Head, of which the followingis a specification This invention consists ot' a mop-head constructedwith one or more series ot studs or projections arranged along the outerside of the handle-socket, and a collar with notches corresponding withthe row of studs, so that it may slide over said studs along thehandlesocket, or, by a slight lateral movement, be caused to engagewith, and be locked by, any one ot' them, and a clamping-wire secured atits ends to said socket, and arranged so that its motion constantlytends to lock said collar with one or another of said studs.

That others may fully understand our invention, we will particularlydescribe it, having reference to the accompanying drawings, in whichFigure lis a perspective view ot our device. Fig. 2 is a plan ot' thesame. Fig. 3 is a side elevation of the saule.

A is the handle-socket, having at its lower end a slotted cross-head,et, through which the clampingwire B passes, and is kept in place. Theends ot' said wire B are riveted or otherwise secured to a collar, C,which is titted to, and slides upon, the handlesocket A, so that theclamping-wire B may be drawn up toward the cross-head a and clamp themop securely, to hold the clampwire up in ei'ective position. One ormore series ot' studs or projections, c, are placed along the sidesocket A, and the collar O has notchesf,'

correspondingly placed, so that it may slide freely back and forth oversaid studs; but by being partially rotated it will enter the spacebetween two of them and be thereby locked.

Then the mop-cloth is placed between the wire B and cross-head a, thecollar O is drawn up until the cloth is sufficiently clamped, and thesaid collar ina-y then be rotated as dcwill only occupy the saine linewhen said collar has partly rotated and the wire B correspondinglysprung or twisted. The torsion ot' said wire then constantly tends tokeep the collar locked. To facilitate the clamping, I

bevel the notches j' toward the upper side, so that the studs ewillfreely enter from above as the collar is pushed up, and cause therequisite rotation ot' said collar. Therefore, when the mop-cloth isplaced over the clamp-wire it is only necessary to rest the inop endagainst the floor and push downward upon the handle to cause the collarto slide and be locked at the highest attainable point. To release themop the collar must be grasped by one hand and forciblyrotated backwarduntil the notches f and studs e come inline.

Having described our invention, whatwe claim as new is 1. Thehandle-socket A, provided with the studs e e and the cross head c,combined with the clamp-wire B and collar O, with notches for thepassage of the studs e, a partial rotation whereof will cause saidcollar to interlock with one oi' said studs, as set forth.

2. The handle-socket A, provided with the studs c, combined with theclainpwire B and collar O, provided with beveled notches j', so adjustedin relation to the said studs that the torsion ot said wire constantlytends to look said collar and studs and inake said locking automatic.
